BENJAMIN T. CRANDALL, OF CHICAGO, ILLINOIS.

VENTILATOR AND STORM-SHIELD.

Application filed September 8, 1910.

To all whom it may concern:

Be it known that I, BENJAMIN J. CRAN- DALL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Ventilators and Storm-Shields, of which the following is a specification.

My invention relates to an appliance which may be termed a ventilator and storm shield, and the invention has for its object to provide a device of this sort which shall have certain new and improved features, to be hereinafter described and claimed.

One of the principal objects of the invention. to be more specific, is to provide a simple, economical and convenient appliance for use in the window of a dwelling house, office or the like, which, when put in position in the window, will serve the purpose of a ventilator, directing the incoming air upwardly, as should be the case, and also the purpose of a storm shield to prevent the rain or snow from entering the room, although permitting the window sash to be open to a greater or less extent, as may be desired.

A further object of the invention is to provide a device of the character described which can be quickly and, by simple, easily understood manipulations, fitted into a window and removed therefrom, as occasion may demand; which, moreover, will fit windows of different widths and constructions; and which may be folded up fiat for ship ment and convenience in laying the device away when not in use, without, however, necessitating the removal of any of the parts of the appliance.

The invention in a preferred embodiment is illustrated in the accompanying drawings, wherein Figure 1 is a fragmentary elevation of a window, viewed from inside the building, showing the device of my invention applied thereto. Fig. 2 is a sectional elevation taken on line 22 of Fig. 1, looking in the direction of the arrows. Fig. 3 is a perspective view of a portion of the appliance illustrating a preferred form of construction. Fig. 4: a fragmentary sectional elevation taken on line l-4c of Fig. 1. Fig. 5 a fragmentary view in elevation of the appliance looking at the opposite side from that presented in Fig. 1. Fig. 6 is a fragmentary sectional plan taken on line 6-43 of Fig. 4; and Fi s. 7 and 8 are sections taken on, respective y,

lines 7-7 and 8-8 of Fig. 1, looking in the direction of the arrows.

Like characters of reference indicate like parts in the several figures of the drawings.

The appliance consists of a front section, end sections and certain devices for removably securing the appliance in windows of different widths and constructions; the end sections being preferably hinged to the. front section and the latter consisting of two members so related that the appliance is extensible to fit windows of different widths. In the construction shown, the front section is composed of two rectangular frames 10, 11, inclosing the panels 12 and 13, the frames being of wood and the panels of wood fiber. It will be understood, however, that other materials might be used and other construct-ions employed than those described. The frames 10 and 11 are extensibly secured together by the channel plates 1 1, embracing the upper and lower edges of the frame, these plates being secured, as shown, to the frame 10. One of the frames, as, for example, 11, is preferably formed with the slot 15 and a bolt 16 extends through this slot and through frame 10 and receives the thumb nut 17, by means of which the frames may be locked together.

The end members, designated 18, are triangular in shape and preferably consist of wood fiber, although other materials might be employed, and have preferably secured at their inner edges the strips 19 which are hinged to the frames 10 and 11 by means of the hinges 20. Various devices might be employed for holding the end pieces 18 in their extended positions. Preferably I employ the folding struts 21, one for each of the end pieces, which are pivoted in keepers 22 on the frames 10 and 11, the keepers being preferably arranged obliquely with respect to the frames, so that the struts turn in planes oblique to the planes of the end pieces 18when the latter are unfolded.

At the lower outside corners of frames 10 and 11 are the stops 23, preferably formed with the slots 24c and secured to the frames by means of bolts 25 and nuts 26; or any other means may be employed for attaching the stops to the frames which will give them capacity for lateral adjustment.

The stops 23 are preferably on the outside surface of the frames. On the inside of the frames, a little Way above this pair of stops, is another pair of stops 27 pivoted to the frames by the bolts 28 and adapted to be held at any desired angular position by the thumb nuts 29. For convenience of manipulation, knobs or handles 30 are arranged on opposite ends of frames 10 and 11.

The appliance of my invention, constructed as above described, is shown in the drawings as applied to a window of common construction.

In the drawings, 31 designates the inner window sill, 32 the outer window sill, 33 the upper sash, and 3a the lower sash, which runs in guideways 35 formed between the in nor stop strips 86 and the parting beads 37. When my device is applied to the window, the stops 23 bear against the parting bead 37 and the stops 27 against the stop strip 36 or inner side of guideway 35. This engagement holds the appliance in position in the window frame, supposing, that is, that the frames 10 and 11 have been extended so as to bring the end sections against the inner stop strips 36. The stops 23 are made later-' ally adjustable because the parting beads in some windows are set farther back or are narrower than in others. The stops 27 are made adjustable, this adjustment depending upon their angular position, in order to accommodate the appliance to windows having sashes of different thickness. The struts 21, it will be seen, bear against the end pieces 18 and force the same against the faces of stop strips 36. Because of the oblique arrangement of the struts, the further forward they are carried the greater pressure will be exerted by them against the end pieces. Preferably the end pieces are made of some what thin, flexible material, such as the wood fiber mentioned, so that these parts of the appliance can be made to bind against the window frame. In order to increase this bind, the outer surfaces of the end pieces may be provided with thin strips 38 of rubber or the like. The engagement of the end pieces 18 with the window frame helps to hold the appliance firmly in position. The frames 10 and 11, constituting what has been termed the front section, may be clamped together by means of the thumb nut 17.

It will be seen that the extensible construction of the front section is a desirable feature, not only because it allows the appliance to be used on windows of different widths, but also so that a close engagement may be obtained between the end members 18 and the window frame. The outer edges of the end members 18 lie close to the lower sash, but, with a proper adjustment of stops 27, they will not interfere with the movement of the sash, which can be moved up or down so as to vary the ventilation of the room. The close engagement of the appliance with the window frame, and particularly'the binding engagement of the preferably thin and flexible end members 18 against the stop strips 36, or equivalent portions of the window frame, effectually prevents rain or snow from entering the room when the lower sash is in a proper posit-ion, even though it may be raised considerably from the sill.

While I have shown and described my invention in the form which I consider most suitable for use under ordinary conditions, it will be realized that modifications might be devised without departure from the spirit of my invention. Therefore, I do not limit myself to the particulars of construction shown and described, except so far as the same are made limitations on certain of the claims herein.
